Step 1: What reduces groupthink?
Classic remedies include a leader staying {impartial}, encouraging dissent (devil’s advocate), inviting outside opinions, using subgroups, and delaying premature consensus.
Step 2: Evaluate options.
(A) Effective (thus NOT an answer). Leader impartiality reduces conformity pressure.
(B) Effective (thus NOT an answer). Accountability reduces mindless concurrence.
(C) Not effective. A leader unilaterally deciding bypasses deliberation rather than improving the group’s decision process; it does not “minimize” groupthink within the team’s dynamics. $\Rightarrow$ Select.
(D) Not effective. Pushing for quick consensus fosters the very symptoms of groupthink (suppressed dissent, illusion of unanimity). $\Rightarrow$ Select.
Conclusion: (C) and (D) would {not} be effective in minimizing groupthink.
